Calvin Harris changes his mind like a girl changes clothes.

After publicly declaring that he would left swipe Taylor Swift on Tinder because she's "the opposite of my type," the DJ du jour seems to have had an abrupt change of heart,

According to TMZ, Harris and Swift are now an official couple after the couple met via the Haim sisters—Taylor's best friends.

After recording Pray to God with Haim, Calvin got close to Taylor and that’s when he decided to swipe right and fell head over heels in love. However, more cynical sources claim this is mainly a business move for Harris.

“They believe Calvin has developed feelings for Taylor, but they say he's wired for success and there's no hard dividing line separating his personal life from business,” one source says.

What do you think? Harris Swift love match? Or, is it all just about the publicity?
